A.A.A.S. SYMPOSIA

While stocks are available

In a recent report (A.A.A.S. Bulletin, February, 1946) the Office of the Permanent Secretary re-

ported on the stocks on hand of the A.A.A.S. Symposia. The Symposia Series were inaugurated in1938 and 21 titles have been published to date. Each symposium quickly established recognitionas a foundation work in its field . . . each will continue to be an important source and reference foryears. Already 5 of the earlier titles are out of print and stocks of the remaining titles are beingsold at a rapid rate.

Outstanding New Scientific Books

ATOMIC AND FREE RADICAL REACTIONSBy E. W. R. STEACIE, National Research Laboratories, OttawaAmerican Chemical Society Monograph No. 102The behavior of atoms has been and will long continue to be one of the primary concerns of science. Any capablyprepared critical presentation of information relating to such basic phenomena is certain to command widespread interestand appreciation.The nature and purpose of this valuable treatise are well explained in the preface. "The 'reactions' of chemicalkinetics and photochemistry are frequently not simple, but rather consist of a series of elementary steps which ofteninvolve atoms and free radicals. Such elementary reactions are therefore of major importance in explaining themechanism of thermal and photochemical reactions. As information concerning elementary reactions is widely spreadthroughout the literature of chemical kinetics, photochemistry, pyrolysis, etc., it is usually very difficult to assemblethe existing data on any given reaction. This book is an attempt to bring together such data, and to treat the reac-tions of atoms and radicals in their own right, rather than as an incidental part of the mechanism of more complexchanges." Most of the discussions pertain to organic elementary reactions occurring in the gaseous state.A most significant volume for technical and institutional libraries, research, laboratories, and private reference shelvesof those interested in the newer concepts of modern chemistry and physics.548 Pages Illustrated $8.00

PHYSICAL CONSTANTS OF HYDROCARBONSVOLUME lll: Mononuclear Aromatic CompoundsBy GUSTAV EGLOFF, Director of Research, Universal Oil Products Co., ChicagoThis important new book is the third in a series of five volumes which will serve as an exhaustive catalog of hydro-carbon compounds and their properties. Volume III contains the structural formulas and complete data on the boil-ing point, melting point, density, and refractive index of the benzene series of hydrocarbons. This highly importantgroup of substances forms the very core of organic chemistry. Knowledge of their physical properties is, therefore,indispensable in all branches of industrial research; it is especially necessary for those in the coal-tar, dye and petroleumfields. Every technical library and organic research chemist will find particular need for this volume of the series.674 Pages American Chemical Society Monograph No. 78 $15.00

ITHE ELECTRON MICROSCOPESecond Edition, Revised and EnlargedBy E. F. BURTON, Head of Department of Physics, University of Torontoand W. H. KOHL, Formerly Chief Engineer, Rogers Radio Tubes Ltd., TorontoJust published-a completely revised volume covering all significant advances in the field. This follows the notablysuccessful first edition of The Electron Microscope. The new edition includes detailed descriptions of improved typesof electron microscopes, and new techniques for examining colloidal substances. Contains 23 full-page plates, some ofwhich are among the most striking electron micrographs ever published. Scientifically-minded readers with an eye tothe future will find this book a valuable addition to their libraries. Contains a complete bibliography of literaturepertaining to the electron microscope.325 Pages Illustrated $4.00

cabMAGARCCompletely Automatic - Magnetic Feeding

CARBON ARC LAMPA new principle in carbon arc microscope lamps. . .Magnetically controlled feeding of carbons assures con-tinued, positive performance throughout the life of thecarbons.

The MAGARC Has These Outstanding Advantages:The feeding of the carbons is completely automatic in theexact ratio of their consumption....The gap of the arm-the distance from the tip of the posi-tive to that of the negative carbon-is continuously andautomatically adjusted, throughout the entire period oftime required for the consumption of one pair of carbons(about 1 /2 hours).Corrective manual adjustments are not necessary."Jumping" of the arc does not occur. Current consump-tion for which the lamp has been designed (10 amperes)is high enough to extend the area of highest intensitythrough practically the entire area of the cross sectionof the carbon.Current consumption and light intensity are maintainedat a relatively constant level.Distance from the light source to the illumination lens ismaintained, and the entire illumination system of a com-plex photomicrographic apparatus remains in alignment.Changing of carbons is simple and safe.Can be used on direct or alternating current. With A. C.a selenium rectifier is interposed in the circuit.

SEMENTS

NOTE: The arc lamp without illumination lensand stand can be supplied separately foruse with optical benches for photomicro-graphy or micro-projection.

A PERSONAL SERVICEFor Scientists

Scientists no less than other Americans are facedwith personal reconversion problems. In keepingwith its policy of giving maximum service to allscientists, SCIENCE has expanded its personal clas-sified advertising section. An announcement inSCIENCE of availability for a more responsible posi-tion, is a dignified and effective method of securingprofessional advancement. The advertiser's identitymay be protected adequately through the use of abox reply address.

Readers of SCIENCE are invited to use the new sec-tion, PERSONNEL PLACEMENT, as a means of detail-ing their qualifications. Those scientists now beingdemobilized from the armed forces or seeking newpositions because of termination of war employmentwill find it an economical way to solve their employ-ment-problems. Employing officers of colleges, uni-versities, and industrial research laboratories will like-wise find this service valuable for attracting qualifiedpersonnel. For complete details see page 18 of thisissue.
